Abstract

The deleterious ecotoxicological influence of Sniper® a dichlorvos-based pesticide was evaluated on non-target environmental receptors – onions – (Allium cepa L) and snails – (Archachatina marginata). The mean effective concentration (EC50) of Sniper® was 7.07 ± 0.08 mg/L for Allium cepa L, with a safe limit estimated at 0.707 ± 0.04 mg/L, while the mean EC50 for Archachatina marginata was 0.762 ± 0.04 mg/kg with a safe concentration of 0.0762 ± 0.02 mg/kg. The Ecotoxicological Risk Assessment Matrix (ERAM) was used to evaluate the deleterious ecological consequences resulting from exposure to the test pesticide. The risk level designated for Sniper® in the Allium cepa L and Archachatina marginata bioassay was E3 or 15 (P; E; C) and E4 or 20 (A; E; C) respectively, which was considered moderate to high risk to plants (P), animals (A), the environment (E) and community (C) based on the frequency of application / exposure. The results from the study implied that continuous exposure and misuse of Sniper® could pose significant risk and damage to non-target plants, soil dwelling species and humans.
